My family has been praying this prayer called THE CHRISTMAS NOVENA for a long time.
It starts on St. Andrew's feast day (Nov 30th) and ends on Christmas Eve. It is prayed 15 times a day. It can be prayed all at one or five times three times a day like the Angelus.
Hail and blessed be the hour and moment in which the Son of God was born of the most pure Virgin Mary, at midnight, in Bethlehem, in the piercing cold. In that hour, vouchsafe, O my God! to hear my prayer and grant my desires,
[here mention your request]
through the merits of Our Savior Jesus Christ, and of His Blessed Mother. Amen.
